Using WhereHas in Laravel Polymorphic Relations

Techniques like these are important to document because we bump into them frequently, but not frequently enough to have it memorized!

It seems like once every project I find myself googling "Laravel Polymorphic WhereHas", combing through one result after another, frustratedly repeating "How do I do this???".

While there isn't a first-party supported solution, I wanted to document what has been working for me, so I don't have to continue searching StackOverflow!

Programming for your Future Self

If you are anything like me, you may find yourself hacking on a variety of different applications during a given week. Occasionally I get the luxury of working on a single app, which gives my brain the freedom to immerse itself into the details of the program. However, inevitably at some point I have to set the project aside and fire up a different one… perhaps one that was written months, or even years ago.

Several thoughts have repeatedly surfaced as I re-familiarize myself with an old project. Instead of having to collect them each time, I thought I’d write them down here, to serve as a reminder.

Sorting Parent Eloquent Models by a Child Relationship

Recently I had a situation in a Laravel app where I needed to sort a collection of parent models by a particular value in a BelongsTo() relationship field.

It’s fairly simple to sort the opposite direction, meaning, to sort all the related models that belong to a parent model.

Simplifying Conditional Expressions

As I’ve been reading through Refactoring by Martin Fowler, I’ve found it helpful to rewrite some of the examples from the book in PHP in order to cement the concepts into my mind. While Martin’s examples are primarily in Java, I’ve found an overwhelming majority of the concepts apply to PHP, which is where I spend most of my programming time.

In today’s article, I will attempt to rework the Simplifying Conditional Expressions (pp. 237-270) section into a handful of PHP-based examples.

Replace Conditional with Polymorphism

Polymorphism is an extremely helpful technique to master. Take a look at this article to see it implemented in a Laravel application:

If you've ever done any research into refactoring, or programming in general, you've most likely heard the term "polymorphism". When I first came across it, I have to admit, I was intimidated.

Now that I've become more familiar with the concept, I can assure you, the word itself is more complicated than the underlying principle!

Refactoring Techniques: Extract Method

A while back, I’d thrown out a question in the Laravel Slack channel asking people what the “must-reads” were for devs. Along with the obvious Uncle Bob books, someone (I believe it was Matt Stauffer) mentioned Refactoring - Improving the Design of Existing Code by Martin Fowler. I looked it up on Amazon and while it was available, I found myself questioning whether a book that was dated 1999 would have any validity in the “modern” coding world I find myself in… not to mention that it didn’t appear to be written for PHP, which is the primary language I use.

I’m glad to say that I put aside my doubts, followed the recommendation, and picked up a copy!

Initially I was disappointed to see that the examples are written in Java, a language I know nothing about. However, I’ve been surprised to see how the broader concepts, such as organization and classes, relate very similarly to what I find myself dealing with in the PHP/Laravel world.

Diving Into a Laravel Audit

Recently the Zaengle team was asked to look over an existing Laravel application and give a review of the overall state of the code. We were to act as an independent third party, between a new studio who had inherited the codebase, and the client, who was anticipating launching the product. The studio had some concerns about the quality of the code and wanted an independent review prior to picking up development on the project. Here are a few thoughts on the process I followed and several takeaways I had from the experience!
